Darke also confirmed that many of the items were the same as those included in Radar's list.

She told MediaGuardian.co.uk that Style magazine had decided to run a piece on the theme and invited contributions from friends, contacts and colleagues.

The Sunday Times' "50 Reasons..." piece had separate men's and women's lists with 25 items each, while Radar had a single list with 100 entries.

Darke said the items that were the same as on Radar's list came from an unnamed contributor and the magazine ran them without checking.

Some of the listed items the Sunday Times ran were adapted for the UK.

Number 58 on the Radar list, "Have taken more than one cell phone picture of your genitals", becomes on the Sunday Times men's list, at number 21, "Have ever taken more than one mobile-phone photograph of your genitals".

Similarly, number 78 in Radar - "Own all 24 volumes of Now That's What I Call Music!" - becomes in the Sunday Times women's list "Own 27 volumes of Now That's What I Call Music!".

The Radar magazine executive editor, Aaron Gell, said: "Although we never like to pile on when one of our fellow hacks gets in a jam, we'll take it as a sign we need to dust off our plans for Radar UK."
